Seriously? The people pointing out how the country is heading down a massively idiotic path because Rupert Murdoch would like us to are the UK's biggest problem?

I'm going to list a few other candidates for the UK's biggest problem:

* The pound plummeting like a rock.

* Xenophobia, bordering on fascism, being advocated by the press.

* The gradual, quiet, handing of the NHS to private companies.

* Ever growing demand for food banks, most notably by people working jobs that don't pay enough to fulfil basic needs.

* The only vaguely viable opposition to the government self-destructing right when they're needed most.

But sure, its definitely people complaining that are the problem.

lack of confidence may well cause remainers to be negative.

Are you suggesting that "remainers being negative" is causing lack of confidence. That puts the cart before the horse somewhat.
